A MOLD AND A MANUFACTURING METHOD THEREOF
BACKGROUND OF THE INVENTION
The present invention relates to a mold used for such as a masking member which protects a part of an article from a surface treatment. More particularly, the present invention relates to a mold consisting of a board having projecting shape(s) on one side and a reinforcing groove on the other side wherein the depth of said groove is smaller than the thickness of said board.
Said mold may be manufactured by such as the vacuum forming of a plastic board and then said vacuum formed board may be punched or trimmed to obtain said mold. It is important for said punching or trimming that said mold has a flat surface to avoid any gap between said vacuum formed board and the surface of the base when said vacuum formed board is punched or trimmed.
Further, when said mold is used as a masking member, it is important that said mold be closely attached to a part of the surface of an article to be protected from a surface treatment. Still further, said mold should be reinforced to avoid deformation.
DESCRIPTION OF THE PRIOR ART
Hitherto, as shown in FIG. 6, a mold (110) as a masking member consisting of a board ~101) having a pair of vessel-like projections (102), (102) and a reinforcing groove (103) on one side has been provided.
. : .. : . ~

:. . .
Said mold may be manufactured by the vacuum forming of a thermoplastic sheet. When said mold (110) is used as a masking member, said mold (110) is attached onto a part of the surface of an artic]e (111) by inserting said projections (102), (102) into holes (112), (112) of said article (111 ) respectively to protect said part from a surface treatment, as shown in FIG. 7.
Since said reinforcing groove ( 103 ) projects on the other side of said board (101) of said mold (110), when said vacuum formed board (101 ) is trimmed to obtain said mold (110), said vacuum formed board (101) is put on a base (114) of a trimming machine and trimmed by trimming blades ( I 13 ), ( 113 ) as shown in FIG. 8.
Nevertheless, due to said vacuum formed board (101 ) having a gap between the board and the surface of said base (114), it is difficult to trim said board (101) correctly.
On the other hand, in the case that said reinforcing groove (103) is formed on the other side of said board (101), said reinforcing groove (103) projects on one side of said board (101) and if said mold (110) is used as a masking member, said mold (110) may have a gap between said mold and a part of the surface of an article. Accordingly, said part of the surface of said article cannot be completely protected by said mold (110).
SUMMARY OF THE INVENTION
Accordingly, an object of the present invention is to reinforce a mold by forming a reinforcing groove to avoid deformation of said mold.
A further object of the present invention is to improve 1.:

The present invention relates to a mold used for such as a masking member which protects a part of an article from a surface treatment. More particularly, the present invention relates to a mold consisting of a board having projecting shape(s) on one side and a reinforcing groove on the other side wherein the depth of said groove is smaller than the thickness of said board.
Said mold may be manufactured by such as the vacuum forming of a plastic board and then said vacuum formed board may be punched or trimmed to obtain said mold. It is important for said punching or trimming that said mold has a flat surface to avoid any gap between said vacuum formed board and the surface of the base when said vacuum formed board is punched or trimmed.
Further, when said mold is used as a masking member, it is important that said mold be closely attached to a part of the surface of an article to be protected from a surface treatment. Still further, said mold should be reinforced to avoid deformation.
DESCRIPTION OF THE PRIOR ART
Hitherto, as shown in FIG. 6, a mold (110) as a masking member consisting of a board ~101) having a pair of vessel-like projections (102), (102) and a reinforcing groove (103) on one side has been provided.

Said mold may be manufactured by the vacuum forming of a thermoplastic sheet. When said mold (110) is used as a masking member, said mold (110) is attached onto a part of the surface of an artic]e (111) by inserting said projections (102), (102) into holes (112), (112) of said article (111 ) respectively to protect said part from a surface treatment, as shown in FIG. 7.
Since said reinforcing groove ( 103 ) projects on the other side of said board (101) of said mold (110), when said vacuum formed board (101 ) is trimmed to obtain said mold (110), said vacuum formed board (101) is put on a base (114) of a trimming machine and trimmed by trimming blades ( I 13 ), ( 113 ) as shown in FIG. 8.
Nevertheless, due to said vacuum formed board (101 ) having a gap between the board and the surface of said base (114), it is difficult to trim said board (101) correctly.
On the other hand, in the case that said reinforcing groove (103) is formed on the other side of said board (101), said reinforcing groove (103) projects on one side of said board (101) and if said mold (110) is used as a masking member, said mold (110) may have a gap between said mold and a part of the surface of an article. Accordingly, said part of the surface of said article cannot be completely protected by said mold (110).
SUMMARY OF THE INVENTION
Accordingly, an object of the present invention is to reinforce a mold by forming a reinforcing groove to avoid deformation of said mold.
